Sniffer dogs
The animals have helped survey teams investigate the area above the cave complex, which is several kilometres long, searching for possible ways in. The dogs were brought to the site after smelling clothing belonging to the missing children, news agency AFP reported.

Plan for rescue
When they are found, the operation to get the group out of the cave will be long.if they are found alive, to bring them to safety. Experts say it could take weeks,
Heavy rains at this time of year mean long passages might well remain continuously flooded for months.

Earlier in the week local officials said rescue teams were preparing to train the boys and their coach to use scuba gear, in case they had to dive out through flooded areas of the cave.

But navigating their way out would be incredibly difficult and it's more likely food and supplies would be sent in while work continued to find another entrance.

Could take a while but at least they know where they are and alive which is half the battle...

The boys, aged between 11 and 16 years old and are all members of the Wild Boar soccer team, entered the Tham Luang Nang Non cave system on Saturday, June 23, for a team outing, but became stranded in the dark tunnels by a sudden and continuous downpour.
The international rescue operation -- which includes the Thai Navy SEALs as well as experts from the US, China, Australia and the UK -- had been working to reach a large, deep chamber, informally known as Pattaya Beach, where the missing boys were believed to have taken refuge.

That sounds horrific. Whilst they may be able to supply the boys with food, medicines, sleeping bags, etc, the psychological effects of being trapped underground for many weeks in a confined space will be enormous.

I'm wondering about the air down there.... the water has cut them off from the outside, and would expect it to cut off the air to the cavern where they are trapped, but no reports I have seen mention this ?

It's an interesting question. The cavern must be large enough (or sufficiently ventilated from above through small fissures) for the air to have lasted them this long, and obviously they can now be supplied with bottled air.

If they are going to be trapped there for much longer, I would think something might need to be done to reduce CO2 levels.
